00:00At first glance, it seems impossible.
00:01How can a wire thinner than a human hair cut through solid metal
00:05without even damaging the threads on a bolt?
00:07The secret is that wire EDM doesn't cut by force.
00:10Instead, it keeps a microscopic gap between the wire and the metal.
00:14Thousands of high-frequency electrical pulses jump across this gap every second,
00:18creating tiny sparks that instantly vaporize microscopic amounts of metal.
00:22Unlike a saw or milling cutter, the wire never presses against the workpiece.
00:27It simply guides the sparks along a precise path.
00:29Since there is virtually no mechanical contact,
00:32there's no cutting pressure, no distortion, and almost no burrs.
00:36A continuous flow of dielectric fluid washes away the melted particles,
00:40leaving an exceptionally smooth and accurate finish.
00:43This unique process allows engineers to create intricate shapes,
00:47razor-sharp corners, and ultra-precise parts
00:50that would be difficult or even impossible with conventional machining.
00:54That's why industries such as aerospace, medical manufacturing,
00:57and precision tooling are willing to invest heavily in wire EDM
01:02because when absolute accuracy matters,
01:05nothing cuts quite like an electric spark.
